I have an Indmar engine that the long block has been changed to I know not what. Also I can't read the indmar sticker on the valve cover. Can anyone tell me what the firing order is on these engines and a workable timing degrees to start with on this engine?

What brand of Indmar, Ford, Chevy? The answer to that question is needed before anyone can answer your question.
